We combine contingent behaviour with travel cost data to estimate the change in the recreational use value of a National Forest due to quality and price changes. Instead of the usual improvement scenario, a hypothetical deterioration in the conditions of the forest due to a fire is considered. A dataset containing five observations for each respondent enabled the estimation of three models for which the number of scenarios differed. The results show that visitors are sensitive to price and quality changes and that in the forest fire scenario the intended number of trips would be reduced and that respondents would experience a welfare loss. Signs of inconsistency between preferences expressed by revealed and intended behaviour were found. This research also provides some indications that strategic bias affects answers to price changes.  相似文献

This contribution first traces the development of the distribution system in China from state monopoly to one which permits the limited participation of foreign ventures, and examines the problems faced by foreign investors in managing the distribution channels under such a transitional economy. Due to China's abundance of linguistic, cultural and economic differences, combined with growing territorialism at the provincial level, different problems may be encountered in different citieslregions, and therefore foreign investors need to modify their distribution strategies accordingly. Detailed case studies are provided as illustrations.  相似文献

This paper offers a model to describe the way in which female expatriates develop relationships and utilize those relationships to become cross-culturally adjusted. This model includes three predictive components affecting cross-cultural adjustment. The first includes the factors affecting whether a woman is able to form relationships on the expatriate assignment. These antecedents can include the female expatriate's personality, the cultural norms towards women, her language skills and the availability of possible opportunities for interaction. The second component includes the various sources of social interaction and social support (e.g. family members, and host national colleagues). The third component describes the nature of a female expatriate's social interaction and social support (e.g. emotional, informational and instrumental). Practical considerations for multinational organizations sending female expatriates are offered.  相似文献

A growing body of research on informal settlements considers the experiences of children, but seldom outlines the daily parenting experiences of adult men and women. At the same time, policy on housing in South Africa points to the ways in which the ‘eradication’ of informal housing will help provide children with better futures. This article explores the social relation of parenting within an informal settlement in Durban, South Africa, bearing in mind the broader difficulties of parenting in poverty, and points to ways in which the material qualities of informal settlements contribute to feelings of anxiety in parents. It questions how these experiences might differ from or be similar to those of parents who live in generic contexts of poverty (but not necessarily informality). It concludes ultimately that living in an informal settlement does actually contribute to particular parental anxieties, but that there is no guarantee that informal housing eradication will remove these concerns.  相似文献

This paper investigates the effect of intra-firm Research and Development expenditure and inter-firm collaboration on firm performance. It is proposed that R&D expenditures enable a company to improve knowledge and assimilate the exchange of information within non-routine collaboration activities. The hypotheses are tested by an empirical study on inter-firm technical collaboration in Japanese Automobile firms during the years 1975–1995, using the method of first-order auto-regression on a panel data set. The findings indicate that R&D expenditure increases performance, but do not allow clear conclusions on the effects of collaborations.  相似文献

The hypercube is a spatially distributed queuing model based on Markovian analysis approximations, used to analyze the configuration and operation of server-to-customer emergency systems. In the present study we adapted the model to analyze emergency medical systems (EMS) on highways, which operate within particular dispatching policies. The study takes into consideration that: the emergency calls are of different types; the servers are distinct (e.g., rescue ambulances, medical vehicles); only certain servers in the system can service calls in a given region (partial backup); and, depending on the type of call, one or more identical or distinct servers are immediately dispatched to service such calls (multiple dispatch). We also consider that the arriving calls take place either along the highway or at the home location of a server – in which case the server does not need to travel to the call location. Finally, we analyzed the computational results of applying such an approach to the case study of an EMS operating on Brazilian highways.  相似文献

Housework and the Wages of Young, Middle-Aged, and Older Workers   总被引:1,自引:0,他引:1  
This article uses samples of young, middle-aged, and older married workers drawn from the Panel Study of Income Dynamics to examine whether the effect of housework time on wages differs among these age groups. Results from OLS, fixed effects, and panel data instrumental variables models show that young and middle-aged wives are the only groups for which the authors find consistent evidence of a housework effect on wages. Each additional hour of housework reduces their wages by 0.1–0.4%. Additionally, the analysis finds evidence that for young workers, housework time is an important determinant of the male/female wage gap. (JEL J16 , J22 , J31 )  相似文献

Little is known about the form and or magnitude of compensation provided university-based scientists working on firm R&D. This is unfortunate, given the important role that university-based scientists play in R&D, and the growing literature concerning compensation and innovation. This paper sheds some light on these issues by examining the compensation of university-based scientists involved with 52 biotech firms that made an initial public offering between March of 1990 and November of 1992. Although the stock holdings of the university scientists are of particular interest, additional forms of compensation received by the scientists are also examined.We find that approximately 10 percent of the university-based scientists affiliated with these companies hold sufficient options or stock to require disclosure at the time of the public offering. A far larger proportion has an equity position in the firm. In many instances the scientists also receive consulting fees or salary from the firm and enter into licensing agreements with the firm. In addition to providing information concerning the compensation of university-based scientists, the empirical work suggests that the rewards to science can be significantly greater than previous work would suggest.  相似文献

During the 1990s, foreign direct investment flowed into Latin America at an unprecedented rate. Capital inflows associated with privatizations and private mergers and acquisitions (M&As) rose steeply. Drawing on original firm–level transactions data, this article examines the extent to which UK enterprises participated in the Latin American privatization and private M&A boom. The authors conclude that, relative to their counterparts in many other major industrial countries, UK enterprises adopted a cautious stance, largely eschewing privatization opportunities and concentrating M&A activities on relatively few operations, sectors and countries, in order to strengthen product and market positions. Moreover, the strategic logic guiding the most important corporate acquisitions centred on gaining access to domestic markets rather than attempting to create global export platforms.  相似文献
